Alliance System in Europe Before World War I (1914)

Alliance System in Europe before World War I (1914). The diagram illustrates the rival alliance blocs—the Triple Alliance (Germany, Austria-Hungary, and Italy) and the Triple Entente (Britain, France, and Russia)—along with the Balkan tensions and treaty network that contributed to the outbreak of World War I.

Balkans

Map of the Balkan Peninsula

The Balkan Peninsula in Southeastern Europe. The region has historically been characterized by ethnic diversity, nationalism, and strategic competition among major powers, earning the title ‘Powder Keg of Europe’ before World War I.

The Balkans (/ˈbɔːlkənz/ BAWL-kənz, /ˈbɒlkənz/ BOL-kənz), corresponding partially with the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Musala, 2,925 metres (9,596 ft), in the Rila mountain range, Bulgaria

Why the Alliance System Was Important

By 1914, Europe had effectively split into two rival camps.

Triple AllianceTriple Entente
GermanyBritain
Austria-HungaryFrance
Italy*Russia

*Italy later joined the Entente Powers in 1915.

Consequence

The alliance system meant that a conflict involving one nation could quickly involve many others, turning a regional dispute into a continental war.


Immediate Trigger of World War I

On 28 June 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by a Serbian nationalist.

Chain Reaction

  1. Austria-Hungary declared war on Serbia.
  2. Russia mobilized in support of Serbia.
  3. Germany backed Austria-Hungary.
  4. France supported Russia.
  5. Germany invaded Belgium.
  6. Britain entered the war.

As a result, a local Balkan crisis escalated into World War I.
